Abstract: Disclosed are a display device and a method for operating pixels of the display device. The display device comprises: a light-emitting element; and a pixel circuit configured to control the light-emitting element, wherein the pixel circuit includes: a capacitor connected to and disposed between a first node and a second node; and a driving transistor including a gate electrode connected to the second node; a first electrode receiving a high-potential driving voltage; and a second electrode connected to a third node, wherein the pixel circuit is configured such that the same voltage is supplied to the first node and the second node during at least a portion of an operation period of the pixel circuit. Thus, occurrence of a reference voltage related short-circuit in the light-emitting element of the pixel circuit is suppressed to prevent occurrence of defective image display in each pixel and to improve reliability thereof.
